A particle moves along a line so that its position at any time t20 is given by the function s(t) = -16t? + 60t + 100, where s is measured in feet and t is measured in seconds (a) Find the displacement during the first 5 seconds. (b) Find the average velocity during the first 5 seconds. (c) Find the instantaneous velocity when t = 5. (d) Find the acceleration of the particle when t = 5. (e) At what value or values of t does the particle change direction?
